I am desperate to speak to Mr Benn about exactly how a retrospective tax can cut CO2 emissions.
My car produces 202 g/km. If they increase tax to £400 it will still produce 202 g/km. If I decide to sell it and buy a prius then someone will buy it, they will use it, and it will STILL produce 202 g/km. If the price of cars like this plummets because of the tax then I won't be able to sell it for another car, i'll be forced to keep it and it will STILL produce 202 g/km. And it's not as if the tax will persuade me to use it less because it is irrespective of milage.
The only way they can cut CO2 in this manner is to tax so unbelievably, stupidly, increadibly, highly that it is better to scrap a £10,000 used car and buy a yaris diesel than pay the tax. And £400 per year isn't even close.
Somebody please explain where the CO2 saving is coming from?
